@alfcin61 Welcome to Connect! What a frightening experience to have fainted at work, you received good medical care quickly and now have a shiny new pacemaker. Thank you @gloaming, @lak1967, and @jc76 for sharing your knowledge and experiences. Alfredo, you are getting used to your new pacemaker and so is your body, your doctor said that you were healing nicely. Be sure to ask your doctor about the anxiety, which is quite common, he/she may have suggestions. Along with that, anxiety has been discussed and studied, there are articles, studies and discussions you may want to read. Type "mayo pacemaker anxiety" in your browser to see and perhaps read what has been written. I have an ICD named Buddy for arrythmia acquired after electrical issues developed following a septal myectomy. Alfredo, will you be returning to work soon? Have you had heart issues before this experience? Where it is it implanted - there are several types. You may choose to read the following link about pacemakers; it may help generate questions to ask your doctor. https://www.mayoclinic.org/tests-procedures/pacemaker/about/pac-20384689
